FREDERICK E. KOHLER, OF CANTON, OHIO, ASSIGN OR OF ONE-HALF OF HIS RIGHT TO ISAAC HARTER, OF SAME PLACE.

HORSE-RAKE.

SPECIFICATION forming part of Letters Patent N0. 225,290, dated March 9, 1880.

, Application filed October 28, 1879.

To all whom it may concern:

Be it known that L-FREDERIGK E. KOHLER, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Horse-Rakes; and I do hereby declare the following to be a full, clear, and exact description of the invenion, such as will enable others skilled in the art to which it ap- Fig. 41s a'detail view of the lifting devices.

Fig. 5 is an enlarged view of the devices for attaching the rake-teeth in position. Fig. 6 is a perspective, and Fig. 7 a rear, view of the tooth-clamp. y y

In the drawings, A A represent the carrying-wheels of the rake. B is the axle and rakehead upon which the wheels are mounted. The draft-frame is composed of the shafts C C and the cross-pieces D D. The frame is hinged to the axle at D D 7 E is the drivers seat.

Having experienced much difficulty with the seats as ordinarily constructed and supported, I'have devised and shown an improved method of mounting and supporting the seat upon a rake.

My device consists of a standard or how, the legs E of which are secured to the rear cross-piece, D. Upon the top of the standard a U-shaped spring is placed, whose arms are respectively secured to the top of the standard and to the bottom of the seat. A brace, E extends from the top of the standard or how E E to the front cross-piece, D. When thus mounted the seat is securely supported, but at the same time is provided with sufficient flexibility of movement.

G G represent the rake-teeth, which are constructed and attached to the rake-head B in the following manner: Each tooth, near its heel or rear end, is bent to form an arm, g, substantially at right angles to the plane occupied by the body of the tooth. The army is bent to form a shorter arm, 9, projecting in a line substantially parallel with the body of the raketeeth. G represents a clamp for holding the teeth in proper position against the rake-head. This clamp is constructed substantially as shown in Figs.5, 6, and 7. g is a recess formed in the back of the clamp to receive the arm g of the tooth. g is a rib projecting from the front side of the clamp, and in this rib there is formed, preferably, a recess, 9 as shown in Fig. 6. g is a hole in the upper part of the clamp for the reception of a bolt, and -9 is a stud projecting from the rear side of the lower end of the clamp, and which, when the clamp is in position, is inserted in a corresponding aperture in the rake-head, to prevent the lower end of the clamp from slipping laterally.

g g are lateral walls attached to or formed. with the clamp G, to hold the rake-tooth steadily in position and prevent any lateral 7o oscillation of the same.

'When the tooth is clamped in position the shorter arm, g, prevents the tooth from escaping from the clamp, although the tooth can oscillate vertically upon the arm 9 as a pivot, 7 5 situated in the groove or recess 9 G is a staple-bolt passing through the rakehead and through the aperture 9 of the clamp, the staple 9' being situated (when in position) in the recess 9 The bolt is secured in place by means of a nut, 9 on the opposite side of the rake-head.

His a bar which is situated a short distance in rear of the rake-head, and through which the teeth respectively pass. This bar supports the body of theteeth, which are situated in slots k, that permit the teeth to oscillate vertically to a limited extent, but do not permit them to moveso far as to escape from their work.

I I represent my improved braces for supporting the bar H behind the rake head. These braces I are constructed of two projecting arms, t i, and a vertical bar, i, the whole brace being substantially U-shaped in form, 9 5 as shown in Fig. 5. r I

K represents the gleanerbar, suspended above the rake-teeth and resting upon the same. This bar is provided with two or more small rollers, 70 k, resting upon the rake-teeth, 10o

and which serve to greatly decrease the resistance of the teeth upon the bar when being raised. The rollers are suspended in brackets is, depending from the lower side of the gleaner-bar.

The bar K is hinged to the drivers seat by means of upwardly and forwardly projecting pieces K K, which are pivoted at their upper ends to a cross-piece, K secured beneath the drivers seat E.

The rake-teeth are elevated from the ground, when desired, by the following devices: L is a curved arm rigidly attached to the upper side of the rake-head B, and projecting above and to the rear of the same.

M is a lifting-lever of peculiar construction. (Shown distinctly in Figs. 2, 3, and 4.) It is formed with an upwardly-projecting handle part, m, and a backwardly-projecting curved arm, m. At or near the angle between the parts on and m the lever is pivoted to the frame of the machine on a pivot,*m which is mounted in standards or lugs m The'arm of the' lifting-lever is connected with the arm L on the rake-head by means of link N, pivoted to both of said parts. This connecting-link N is preferably constructed with forked ends which inclose the arms m and L, respectively.

When it is desired to elevate the teeth from the ground the driver pulls backward upon the handle on, which action throws downward and forward the arm m" and the link N and pulls forward upon the arm L, which turns the rake-head B and lifts the teeth. The parts are then substantially in the position shown in Fig. 3, the pivotal point m between the arm m and the link N being so low down that the rake-head and teeth are easily held in their upper position until it is desired to again lower them.

The operation of lowering the teeth and the holding them to their work can be assisted by the foot of the operator, there being a stirrup or arm, 0, projecting laterally from the lever M near its lower end to receive the foot. This stirrup or arm may be welded or bolted to or formed in one piece with the lever.

P P are braces running from the point where the lifting-lever is pivoted to the frame backward to the rear sill or some other fixed part of the frame, where they are firmly bolted. These braces make the lever perfectly secure in its position and render it much more effi cient than when used without the braces.

It will be seen that when the rake is in the position shown in Fig. 2 the pivotal point at which the lever is pivoted to the link N is above the line between the point m where the lever is pivoted to the frame, and the point at which the link N is pivoted to arm L, and that when in this position the parts are so related to each other that the rake head and teeth are automatically locked in raking position until the lever M thrusts the intermediate pivotal point below the line of the outer pivotal points.

The arm m is provided with a series of perforations, n, whereby the pivot between said arm and link N can be adjusted to suit different drivers or to compensate for wear and strain.

The brackets I I vare intended to take the place of the cast-iron devices usually employed to support the slotted tooth-bar.

My improved brackets are bent from a single piece of metal, preferably wrought, and constructed and combined with the other parts in such manner that they can be readily repaired and replaced by any blacksmith.

What I claim is- 1. The combination, with the rake-head and the slotted supporting-bar H, of the braces I, formed of the horizontal arms *5 i and vertical part i, substantially as and for the purposes set forth.

2. The combination, with the rake-tooth G and the staple-bolt G projecting through the rake-head, of the clamp G, having the horizontal recess g and the pin substanlifting devices, consisting of the lever M, pivoted to the draft-frame, and the link N, pivoted to the tooth-frame, of the metal pieces P P, rigidly secured to the lifting-levers at the front end and to the draft-frame at the rear end, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of- October, 1879.
